   * enhancement: sb-ext:save-lisp-and-die on Windows now accepts
     :application-type argument, which can be :console or :gui. :gui allows
     having GUI applications without an automatically appearing console window.
+  * enhancement: reduced conservativism on GENCGC platforms:
+    conservative roots that point to unboxed pages must be tagged
+    pointers to the start of a valid-looking object, not merely point
+    to within the allocated part of the page, in order to pin the page.
   * bug fix: Windows applications without the console window no longer misbehave.
     (patch by Wilfredo Velazquez, lp#1256034).
   * bug fix: modular arithmetic optimizations do not stumble on dead branches
     with bad constants. (reported by Douglas Katzman)
   * bug fix: CLISP can be used again as a cross-compilation host.
     (Thanks to Vasily Postnicov, lp#1261451)
+  * bug fix: run-program crashed with :directory nil. (lp#1265077)
